桥随路降法治理桥头跳车

Treating Bridge Jumping by the Method of Bridge Descending with Roadbed Sinking

分析软土地基上路堤与桥梁的沉降差异及跳车的原因,采用桥随路降的治理方法,应用柱式升降桥墩来调控桥面高程,使桥面降落高度与路面沉降量一致,保持道路竖曲线顺畅,消除桥头跳车.

The sedimentation rate difference of roadbed and bridge, and the causes of bridge jumping are analyzed, and based on which the method of bridge descending with roadbed sinking is proposed. The presented method involves applying cylinder gradient abutment to control bridge level so that the uniform magnitude between bridge descending and roadbed sinking can be obtained, and road vertical curve is thus kept smooth and bridge jumping eliminated.
